On the toll road between Tecate and Tijuana on Wednesday, trucks roared past Tom Fremantle and his dog, Pancho. The 42-year-old Englishman was walking west, on the verge of completing a 1,000-mile walk along the U.S.-Mexico border that began Nov. 9th in El Paso.

“The scenery is a little bit Scottish,” Fremantle remarked, as he strolled amid a scenery of tall, barren hills. On this brisk winter day, the sky was filled with fluffy white clouds. “The weather feels like England,” he said.
